Hi folks,
Working on a Latitude E6400.
Model of the motherboard: Dell 0U695R
Model of the memory: F2-5300CL5D-8GBSQ
Model of the CPU: Intel Mobile Core 2 Duo P9700
This laptop always had 2x2GB memory, and I decided to upgrade to 8GB in February of this year to prepare for a conference in April. I purchased G.SKILL's F2-5300CL5D-8GBSQ for this. I installed the memory, and was promptly greeted by the following message on boot:
I tried reseating, no change (except the address/values). Tried using each stick in DIMM A, no problems. Tried my old RAM, no problems. Tried swapping which new stick I used in which DIMM, got the original error again. Then, suddenly, on a try where I did nothing new, voila, it booted up.
While I was uncomfortable with this and expecting the system to crash at any moment, I screwed my back panel back on and left it alone. I was able to use the laptop at the conference in April for a full week with not a single issue. I don't use the laptop frequently, but pulled it out again today to use, and had an unrelated problem for which I tried to open the boot menu.
Boom. Original error is back.
It's possible I could keep trying to boot this thing and eventually it would work, but I'd like some answers. My only theories have been 1) the MOBO isn't providing enough voltage to the memory, or 2) that I have a bad stick of memory. I'm not happy with either of those theories though because 1) CPU-Z says it's giving my old memory 1.8V right now which should be plenty (if I'm reading this right - 1.8V seems high to me), and 2) while the memory was working for the past few months, I had not a single issue with it, which seems unlikely if one of the sticks was faulty.
It seems like the BIOS is testing the memory under certain conditions, and while this memory rarely passes the test for some reason, it passed once, and since I never opened the boot menu again, it wasn't tested again. Now, when I reopened the BIOS, it tried the test again, and of course failed again. What I'm not sure of is why the memory seems to be fine but doesn't pass the BIOS's test. The BIOS is at version A34, by the way, which is the last release for the Latitude E6400.
Let me know if any additional information is needed. Would really like to get this working.
